Tsarin tsaftacewa na tsaftacewa na ultrasonic shine yafi saboda gabatarwar ultrasonic vibration a cikin ruwa mai tsabta, wanda ke haifar da "cavitation" a cikin ruwa mai tsabta. Ƙarfin injina mai ƙarfi wanda “cavitation” ya haifar yana kwasar ƙazantattun injiniyoyi da gurɓatattun abubuwa daban-daban da ke haɗe zuwa kayan aikin. Ultrasonic tsaftacewa ba kawai yana da cavitation sakamako, amma kuma tare da mafi rikitarwa jiki da kuma sinadaran effects.
Abin da ake kira "cavitation" yana nufin yanayin da ba shi da kyau kuma mai yawa lokacin da canjin sautin sauti na raƙuman ruwa na ultrasonic ya yada a cikin ruwa. A cikin yanayi mai yawa, ruwa yana fuskantar matsin lamba mai kyau (kimanin ƴan matsa lamba na yanayi), yayin da a cikin ƙananan yanayi, ruwan yana cikin tashin hankali ko matsa lamba mara kyau. Gabaɗaya, ruwan ya ƙunshi adadin iskar gas. A cikin yanayi mara kyau, kumfa yana girma kuma yana ɗaukar ƙarin Gas ɗin da ya lalace a cikin ruwa; idan aka sake matsawa, kumfa na ci gaba da raguwa. A yayin wannan tsari, motsin ɓangarorin ruwa ya yi daidai da radius mai raguwa a hankali. Don haka, lokacin da radius ya kusanci sifili, saurin motsi ya kamata a ka'ida ya kusanci rashin iyaka. Idan wannan saurin motsi ya tsaya ba zato ba tsammani lokacin da kumfa ke rufe, za a saki makamashin motsa jiki da ke cikin ƙaramin ƙara, wani ɓangare ya zama makamashin zafi, wani ɓangare ya zama ƙarfin matsawa. A wannan lokacin, kalaman girgiza mai siffar zobe yana yaduwa waje daga tsakiyar kumfa da aka rufe. A wannan lokacin, matsin lamba shine dubban yanayi. Idan mitar ultrasonic shine 20KHz, wannan cavitation zai faru sau 20,000 a sakan daya. Sabili da haka, ba shi da wuya a gane cewa raƙuman ruwa na ultrasonic suna da ƙarfin tsaftacewa mai ƙarfi.
